To all whom it may Concern:

Be it known that we, EZRA T. CAMPBELL and BERN- HARD H. NOELTING,citizens of the United States, residing at Nebraska City, in the countyof Otoe and State of Nebraska, have invented certain new and usel'ulImprovements in-ll'ater-l'lotoi-S, 0i which the following is aspecification.

Our invention has relation topthat class oi water motors in which aseries of paddles of preferably rectangular' form are hinged to theconnecting rods of an endless chain of frames rigidly connected at oneof their ends by integral inverted U shaped braces which present a firmbearing surface for the paddles when presented to the current to receivethe impact thereof, the ends of the connecting rods being adapted toengage in corresponding concave recesses in the radial arms of wheelsand effect their rotation.

One of the objects ot' the invention is the production of a currentmotor which is comparatively simple and economical in construction,efficient in operation, and capable of delivering ashore the maximumamount of power possible from any stream in which it may be placed.

The invention consists in the novel construction, combination and arr:ngement of parts as will be hereinafter described.

ln the accompanying drawings in which like parts are designated by likecharacters throughout the several vicws:-Figure l, is a perspective viewof our invention. Fig. l, is a cross sectional view of our invention,cut on the line a a, of Fig. l.l Fig. 2, is a detail perspective view ofour invention, showing the construction of the frames comprising theendless chain for the paddles. Fig. 3, is a bottom plan view of one ofthe paddles hinged to one of the connecting rods. Fig. 3, is an edgeview oi Fig. 3. Fig. 4, is a modification of our invention, showing theconstruction of the frames comprising the endless chain for the paddlesand the manner of securing them thereto when the motor is used as apropeller.

Our invention is described as follows1The numeral 1, represents theframes comprising the endless chain for the paddles. Said frames arepreferably constructed of flat rectangular steel bars 2 transverselyperforated near their ends and rigidly connected at one of their ends bymeans of inverted U shaped braces 3, the purpose of which will be shown.The free ends of said frames are rigidly braced a pre-determineddistance apart by oblique braces 4, which are secured at their ends tothe inner sides of said bars 2 of said frames 1. Said frames aredetachably connected together by bringing them in such a position thatthe perforations in their tree ends register with the perforations inthe opposite ends of adjacent frames, and employing transverseconnecting rods 5, which are passed transversely through saidperforations. The numeral 6, represent shaped braces 3, of the frames.

the paddles of our motor, which paddles are constructed of suitablematerial and are preferably rectangular in shape. Said paddles arehinged to said connecting rods 5 within the bars 2 of said frames l bylongitudinal plates or bars 7, whichare rigidly secured to the underfaces of said paddles and hinged at their eyed ends to said connectingrods 5. The ends of said transverse connecting rods 5 protrudesufliciently beyond the outer faces of the bars 2 oi said frames 1 topermit of engagement in corresponding concave recesses in the radialarms of wheels 9. The radial arms of said wheels 9 are of such a numberand such distances apart with respect to the frames 1 as to permit ofperfectengagement with the ends of said connecting rods 5.

When in use, the free ends of the upper section of the train of paddlesG lie down against the tops of the inverted U shaped braces 3 of saidframes 1 and travel in a direction opposite to that of the current. Thelower section of the train of paddles travel in the direction of thecurrent and are held in vertical position by the inverted U shapedbraces 3 of said frames, which serve as bearing surfaces for the upperhinged ends of said paddles. In this position the paddles receive allthe power of the stream possible. The paddles traveling in the directionof the current are carried up and over corresponding wheels 9, andtravel in a direction opposite to the current, when the paddles lie downagain against the tops of the inverted U Our water motor, when in use,is secured on a catamaran, or a fiat boat, provided with a propercentral walled opening for the paddles securely anchored to prevent itsfloating away.

When we desire very great power, we make the chain of considerablelength so we may use quite a number oi paddles, in which case we erect avertical frame 9*", on the upper and lower rails of which the spools 5,journaled on the ends of the rod 5, run.

1n the modification of our invention, see Fig. 4, which is designed tobe used as a propeller, we dispense with the inverted U shaped braces 3,of the frames 1, and in lieu thereof employ an additional set of obliquebraces with each frame. In this case, the paddles G, are not hinged tothe connecting rods 5, but are vertically braced at the center of thelengths of the frames by curved braces 10, secured at their lower endsto the side bars of the frames and at their centers to the outer edgesof said paddles. The wheels 9, in this case are constructed inaccordance with the wheels for the water motor, and the frames work overthe wheels in the same manner as the frames of the motor.

Having described my invention, what 1 claim as new and desire to secureby Letters Patent, is:-

1. In a water motor, the combination or' a series of frames, eachconsisting of two rectangular bars trans versely perforated ateitherend, and connected at one end by a transverse inverted U sha1 dbrace; oblique braces. their ends secured to the inner ces ol said bars;transverse connecting; rods, one passing through the perforations in theend oi.' each traine. and the perfor-ations in the opposite end el theadjacent trarne: longitudinal bars. hinged to said connecting' rodswithin said frames; rec taugular paddles. their under .laces secured tosaid last mentioned bars, and wheels having radial arms provided withconcave recesses in'tlieir ends, the outer ends olf said connecting`-rods adapted to engage in the recesses ot the radial arms oi' said.vheels and effect their rotation, sub4 stantially as shown anddescribed, and for the purposes set forth.

2. ln a Water motor, the Combination o'l aseries olf frames, eachconsisting ol'two rectangular bars; inverted U shaped braces connectinoone ol' the ends oi said frames: oblique braces, their 'ends secured tethe inner 'faces ot' said frame bars; lneans tor pivotally connectingthe adjacent ends ol said l[rames: rectangular paddles, hingedlongitudinall}.Y te said l'ramesy and wheels having;- radial arinsprovided with recesses in their ends, said wheels adapted te be pnt inrotation by said l'ranies, substantially as shown and described. and ferthe purposes set L'erth.
